Abstract: 1442617 Monocarbides; mononitrides and carbonitrides KERNFORSCHUNG mbH GES FUER 20 Dec 1973 [22 Dec 1972] 59186/73 Heading C1A [Also in Divisions C2 and G6] Monocarbides of at least one of the metals titanium, vanadium, zirconium,niobium,molybdenum, hafnium, tantalum, tungsten, thorium, uranium, plutonium or americium are made by: (a) forming a mixture of carbon with an oxalate of at least one of said metals: (b) decomposing the metal oxalate-carbon mixture by heating the mixture in a stream of a hydrogen containing gas; (c) immediately removing the hydrogen containing gas upon completion of the decomposition reaction and (d) heating the decomposition products immediately after removal of the hydrogen containing gas to an elevated temperature in vacuo to carbothermally reduce the decomposition products and form the monocarbide. Mononitrides and carbonitrides of the above metals and mixtures thereof can be produced by the steps (a) and (b) followed by (c) removing the hydrogen containing gas and feeding a stream of a nitrogen containing gas into contact with the decomposition products and (d) heating the decomposition products immediately after removal of the hydrogen-containing gas in the nitrogen containing gas stream. The preferred carbothermal reduction temperature range is 1100‹ to 1300‹ C. when forming monocarbides; when forming mononitrides or carbonitrides the preferred temperature for heating the decomposition products in the nitrogen containing gas stream is greater than 1500‹ C.

Title: Speed Control System for an Electric Motor
IPC: H02P7/295
Filed: 1968-12-17
Abstract: 1,178,828. Control of D.C. motors. SINGER CO. 17 Dec., 1968 [29 Dec., 1967], No. 59906/68. Heading H2J. [Also in Division G3] A series motor 26, which drives a sewing- machine, is associated with a foot-controller 25 and a three-position manual switch 28. When the sliding member 56 of the switch is in the high-speed position, a lamp 27 is energized and the motor circuit is closed through the footcontroller. Adjustment of the member 56 to the low-speed position lights the lamp, and connects a diode 29 in shunt with field winding 43, so permitting current to flow in the field winding even after a silicon-controlled rectifier 37 in the footcontroller stops conducting during each cycle. The armature 40 develops a larger back E.M.F. which is transmitted to the gate control circuit 38 as negative bias in opposition to the positive bias provided by the potentiometer 39. The motor thus operates over a lower speed range when the field winding is shunted by the diode.

Title: Electronic generation of an analogue clock face on a television
IPC: G04G9/00
Filed: 1978-08-02
Abstract: A circuit generates signals representing an analogue clock face having a circular dial with minutes markers and at least one rotating hand. The hand is produced by mixing line and field rate ramps in differing proportions in a mixer 202 and applying the mixed ramps to Exclusive - OR gates E - OR having differently thresholded pairs of inputs. The output of each gate (Figure 2a) is selected by circuit 208 at a rate of one per second, and a blanking circuit 209 ensures that a line appears in only one quadrant at a time. The circular dial is generated by integrating the line and field rate ramps in circuits LP, FP and mixing them in mixer 212. The mixed parabolic signals are applied to a circle generating circuit comprising two voltage comparators having thresholds modulated by signals LIM, LOM, and SIM.FQ derived from the outputs of the gates E-OR whereby markers are produced. Blanking circuits to blank part of the dial and to define the length of the hand are provided. <IMAGE>

Abstract: A dual circuit hydraulic steering system has a first steering circuit with a valve (6), a pump (12) and two steering conduits (3, 4) leading to the piston rod ends of two steering cylinders (1, 2). A second steering circuit likewise has a valve (6'), a pump (12') and two steering conduits (3', 4') which lead to the piston face ends of the steering cylinders (1, 2). The two steering valves (6, 6') are mechanically coupled to each other on the input side but small pressure differences in conduits 3, 3' and 4, 4' can still occur. When the pressure on the pressurised second circuit conduit (3' or 4') differs from the pressure on the pressurised first circuit conduit (3 or 4), a hydraulic actuator (29') actuates the second circuit valve (6') to counteract the pressure difference, thereby making the second circuit closely follow the first circuit. <IMAGE>

Title: By-pass gas turbine engines
IPC: F02K3/115
Filed: 1979-01-31
Abstract: In a by-pass gas turbine engine operating on an unmixed cycle a core engine 10 drives a fan 12 to produce a by-pass flow in a by-pass duct 16, and a heat exchanger in the form of interconnected vanes 24, 26 spans both the by-pass duct 16 and the jet pipe 20 of the core engine, so that waste heat from the jet pipe 20 downstream of the last turbine stage can be transferred to the by-pass duct. The vanes 24, 26 are preferably formed at least in part as heat pipes. Alternatively, conventional vanes may be provided and may be interconnected by heat pipes. A modification of this type can increase the thrust of an unmixed engine cycle, but in particular, if the cycle is adjusted so that, upstream of the heat exchanger, the pressure of the by-pass flow is greater than the pressure of the hot gas exhaust from the core engine, the modified engine can produce more thrust than an equivalent engine operating on an optimised mixed cycle. <IMAGE>
